Answer: 16.97
<u>Step-by-step explanation:</u>
To find the distance from W to X, you can use the distance formula ...or... draw a right triangle using W and X as the vertices and use Pythagorean Theorem to find the hypotenuse. I will solve using the latter.
The y-distance from W to X is 12.
The x-distance from W to X is 12.
hypotenuse² = 12² + 12²
= 144 + 144
= 288
hypotenuse =
= 16.97
